"Tuesday morning at 8 o'clock is chaos at Rafah Crossing, the Egyptian-controlled entrance to the Gaza Strip. Black-clad Egyptian security forces stand by their trucks, ready if things get out of hand. Aid convoys line up in front of the main gate. Hundreds of Palestinians have already massed before the first checkpoint, yelling at border security in their effort to push through. Off to one side, a group of travelers tries to revive a sick woman who has lost consciousness. Egyptian security look on. Tempers are mounting. This is Day One of a rare three-day border opening."
